“We do not find any correlations with mask mandates”

Emily Oster, Rebecca Jack, Clare Halloran, John Schoof, Diana McLeod:

This paper reports on the correlation of mitigation practices with staff and student COVID-19 case rates in Florida, New York, and Massachusetts during the 2020-2021 school year. We analyze data collected by the COVID-19 School Response Dashboard and focus on student density, ventilation upgrades, and masking. We find higher student COVID-19 rates in schools and districts with lower in-person density but no correlations in staff rates. Ventilation upgrades are correlated with lower rates in Florida but not in New York. We do not find any correlations with mask mandates. All rates are lower in the spring, after teacher vaccination is underway

which pushed Dane County this week not to calculate its percentage of positive tests — a data point the public uses to determine how intense infection is in an area.   

While positive test results are being processed and their number reported quickly, negative test results are taking days in some cases to be analyzed before they are reported to the state. 

Channel3000:

The department said it was between eight and 10 days behind in updating that metric on the dashboard, and as a result it appeared to show a higher positive percentage of tests and a lower number of total tests per day.

The department said this delay is due to the fact data analysts must input each of the hundreds of tests per day manually, and in order to continue accurate and timely contact tracing efforts, they prioritized inputting positive tests.

“Positive tests are always immediately verified and processed, and delays in processing negative tests in our data system does not affect notification of test results,” the department said in a news release. “The only effect this backlog has had is on our percent positivity rate and daily test counts.”

Staff have not verified the approximately 17,000 tests, which includes steps such as matching test results to patients to avoid duplicating numbers and verifying the person who was tested resides in Dane County.

All 77 false-positive COVID-19 tests come back negative upon reruns.
